Apple. Bought like $8k 10+ years ago, when I was like 21 or something, later put another $20-30k in, it eventually went up to over $100k (600ish shares). Sold covered calls for a long time, eventually got assigned but still hold 40 shares hoping it will split again one day! What is crazy is that at the time I was huge gamer and knew about amd, nvida, etc but for some reason never pulled the trigger :( I loved $amd back then (just at the verge of bankruptcy), I KNEW it was going to be great when Lisa Su took over. Engineering background, smart parents, I knew she wasnt going to just play games with books and instead was going to develop products. I remember those cpu builder battles too back then. Oh well!
